r - Is it possible to get the number of rows in a CSV file without opening it?

Question

I have a CSV file of size ~1 GB, and as my laptop is of basic configuration, I'm not able to open the file in Excel or R. But out of curiosity, I would like to get the number of rows in the file. How am I to do it, if at all I can do it?

Answer 1

For Linux/Unix:

wc -l filename

For Windows:

find /c /v "A String that is extremely unlikely to occur" filename
